Electronic Document Display Layout Correction for Image-Text Association
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic document display apparatuses struggle to simultaneously display images and related text across multiple pages, leading to inconvenient user experiences due to layout discrepancies when reflowing text and images in XML-based documents.
Innovation Solution
An electronic document display apparatus with an analysis-and-setting unit that determines if images related to the display range are included, adding an image display region if necessary to ensure the image and its text are visible, and adjusting the display state based on predetermined conditions to optimize layout.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If reflow is performed to adjust line breaks and display positions according to character size, then text display flexibility is improved, but layout consistency with creator's intent deteriorates
Solution Approach 1:
The system performs preliminary analysis of image relationships with text during the layout preparation phase. It identifies images that should be displayed with their related text and pre-arranges them together before actual display, ensuring that when reflow occurs, these image-text pairs maintain their association and are displayed together on the same screen.
2Area of stationary object
If images and text are displayed according to standard reflow layout, then screen space utilization is improved, but user convenience in referring to images deteriorates
Solution Approach 1:
The system merges the image display region with the text display region by adding the image display region to the display range when an image related to the displayed text is not already included. This combining ensures that both the image and its related text are displayed together on the same screen, improving user convenience without significantly compromising screen space utilization.
3Ease of operation
If image display region is added to include both image and text, then ease of referring to images is improved, but display layout complexity increases
Solution Approach 1:
The determination unit performs preliminary identification of images that need to be displayed with their related text. By analyzing the relationship between images and text before layout finalization, the system determines which images should be included in the display range, thereby managing layout complexity through structured analysis rather than ad-hoc adjustments.
Solution Approach 2:
The system automatically adjusts the display layout by adding image display regions as needed, without requiring manual intervention. The determination unit and correction unit work together to self-correct the layout, identifying when images are missing from the display range and automatically incorporating them, thereby reducing the perceived complexity for the user.

AI summary
An electronic document display apparatus includes a display unit and an analysis-and-setting unit including a determination unit and a first correction unit. The display unit displays an electronic document in display layout set by the analysis-and-setting unit. If the determination unit determines that an image related to a display-range text of a display range to be displayed by the display unit is not included in the display range, the first correction unit adds an image display region where the image is displayed to the display range so as to correct the display layout in such a way that the image and at least a portion of an image text related to the image are included in the display range. The analysis-and-setting unit changes a display state of the image displayed in the image display region on the basis of a predetermined condition.
